The 40-Wire Colored Flat Ribbon Cable Jumper Wires (1 Foot) (2.54mm Pitch) is a versatile multi-conductor cable designed for connecting electronic components, development boards, sensors, modules, and other devices in prototype and embedded electronics projects. It contains 40 individually insulated wires arranged in a flat ribbon configuration, making it easy to organize multiple connections while keeping wiring neat and manageable.
With a standard 2.54mm (0.1-inch) pitch, this ribbon cable is compatible with many common pin headers, IDC connectors, development boards, and breadboard-based electronics. The individual wires are color-coded to simplify circuit assembly, troubleshooting, and identification of signal and power connections.
Its flexible construction allows the cable to be routed easily inside project enclosures and around electronic modules, making it particularly useful for Arduino, Raspberry Pi, robotics, automation, and educational electronics projects.

Working Principle
Each conductor in the ribbon cable provides an independent electrical path between connected electronic components.
The 40 wires are arranged side-by-side at a standard 2.54mm pitch, allowing them to be connected individually to pin headers, sockets, IDC connectors, development boards, or other compatible terminals.
The color-coded arrangement makes it easier to identify individual connections, particularly when working with circuits containing multiple GPIO, power, ground, communication, or sensor connections.
For example, different wires can be assigned to:
- VCC / Power
- GND
- Digital Signals
- Analog Signals
- I²C SDA and SCL
- SPI Signals
- UART TX and RX
- Sensor Connections
- Control Signals
Applications
- Arduino Projects
- Raspberry Pi Projects

Usage Tips
- Identify each wire before making connections.
- Keep the cable away from moving parts and high-heat sources.
- Avoid excessive bending or pulling to prevent conductor damage.
- Use appropriate connectors or headers for secure connections.
- Label individual wires when working with complex circuits.
- Verify continuity with a multimeter if a connection is suspected to be faulty.
- Do not exceed the cable’s current-carrying capacity.
